The Drake PC8071 Passive Combiner manual covers the setup of combining outputs from up to eight Audio/Video Modulators or Channel Processors into a single coaxial cable, with specifications including a frequency range of 5-1000 MHz and an insertion loss of 12 dB nominal. It also provides guidance on operation and troubleshooting, including a monitor output at the front panel and details on warranty service for defects in material or workmanship.
Manual Overview
The Drake PC801 Passive Combiner is designed to merge outputs from up to eight audio/video modulators or channel processors into a single coaxial output. It can be mounted in a standard 1-3/4″ H x 19″ W rack space and features a front panel monitor output. For increased capacity, multiple combiners can be linked. The unit operates within a frequency range of 5-1000 MHz, with a nominal insertion loss of 12 dB and a maximum of 14.5 dB. It provides a port-port isolation of 30 dB nominal and 25 dB minimum, and can handle a maximum input of +60 dBmV per input. The impedance is set at 75 Ohms, with a return loss of 16 dB nominal. The monitor test point is set at -20 dB relative to the output. The device meets FCC Part 76 shielding requirements and operates in temperatures ranging from -20° C to +50° C. For troubleshooting, ensure proper maintenance and installation, as improper handling can void the three-year limited warranty. For service, contact R.L. Drake Company with the necessary product and purchase details.
Quick Issues Covered
- Diagnose insertion loss issues exceeding 14.5 dB maximum.
- Troubleshoot port-port isolation below 25 dB minimum.
- Use schematics for tracing monitor output circuit at -20 dB.
